Most newer leaves are clear. Is it ok to take cuttings that have clean leaves and start new plants? Or do you think any cuttings are also infected?

It looks more like an abiotic issue than an infectious disease or insect, so I'd go ahead and use anything.

Thanks. I guessed it could be poor drainage in this pot, it has struggled all summer. Fresh cuttings, fresh pots, easier to keep ov er winter or share

That is what I would do. No idea why the spots are there, but when I get weirdness like that on a plant that propagates easily, I think it's easier to re-start with the best looking parts and discard the old rootball. Best luck getting past the spots!

Reminds me, I initially was given the plant as a gorgeous specimen that got too large on someone's porch and they had no indoor place for it. It dwindled in the library over winter. When I repotted that spring, I found the bottom couple inches of the hanging basket was pure perlite. Odd. But I appreciated the free perlite to add to my potting mix. I may have restarted from cuttings at that point as well.
